Anyone use Littlekickers?

My 22 month old DS has just started going.He has done 3 classes now.He hated the first 2,was reallly clingy and would not join in(totally unlike him as usually v sociable,outgoing and likes running and footballs).I'm told his reaction at first was fairly typical at that age.Last week he was a lot better and enjoyed it a lot more.They learn colours, how to follow instructions, and it is good exercise and something he can do with DH on a Saturday morning.Now he is enjoying it I think we will stick with it and would recommend it.
